setix 0.8.3

Fast data structures for finding intersecting sets and similar strings

=====setix=====

At its core setix provides a "set intersection index", an inverted index data structure designed for storing setsof symbols and fast querying of sets intersecting the given set, with sorting based on the number of intersectionsor a similarity measure.

Additionally, a wrapper for indexing strings is provided in setix.trgm, which implements a trigram index compatiblewith the PostgreSQL extension pg_trgm.
